PP/EVOHPE high barrier film: in recent years, with the change of eating habits, more and more people from the supermarket to purchase small packaging of food, so that the market for food packaging barrier film demand is also increasing.PP high barrier sheet is widely used in food packaging at room temperature, which can effectively enhance the shelf life.
Case: supermarket frozen food, seasoning packaging, etc
PP color sheet: our customers need to customize a variety of color pp plastic sheet, PP sheet, PP roll.Blister pp roll materials, available and moon cake packaging materials are selected from our company’s production of pp color sheet.
1. PP/EVOHPE high barrier film
EVOH is a crystalline polymer with chain structure, which is a random copolymer of ethylene _ ethylene alcohol, so it integrates the good processing property of ethylene polymer and the high gas barrier property of ethylene alcohol polymer.
When ethylene monomer was added, the tensile strength and impact strength of EVOH decreased while the water resistance and processing performance were improved.The barrier of EVOH membrane can be increased by 2~3 times after bidirectional stretching.
In EVOH copolymer, EVOH with different properties can be obtained by changing the content of ethylene monomer and ethylene alcohol monomer.Among them, ethylene monomer provides water resistance and processability, while ethylene alcohol monomer provides barrier, so the content of ethylene monomer increases, so does the oxygen transmission coefficient.For example, when EVOH contains 29% ethylene, its oxygen transmissibility coefficient is 0.1ml. Mm/m2d.mpa, while when ethylene content is 38%, its oxygen transmissibility coefficient is 0.4ml. Mm/m2d.mpa.
EVOH is hydrophilic and hygroscopic due to the presence of hydroxyl in the molecular structure of the resin. Pure EVOH products have high water absorption, which seriously affects the barrier property. Therefore, EVOH cannot be used alone, and is often used as an intermediate material and composite with other materials to prevent its water absorption from affecting its barrier property.And the barrier of EVOH will decrease as the temperature increases.It can prevent O2 and other gases from permeating into the packaging bag, and also prevent the air from escaping from the bag.Its air resistance is 100 times higher than PA and 10,000 times higher than PE and PP.
